A system includes a work vehicle, user interface, and controller. The work vehicle includes a frame, boom, implement, perception sensor, and ground speed sensor. The perception sensor senses an approaching environment. The user interface includes controls and indicators. The controller is coupled to the controls, indicators, perception sensor, and ground speed sensor. The controller receives a command to move the work vehicle, drives the work vehicle, determines a distance to the container, determines the ground speed, determines a boom raising start distance from the container, receives a command to raise the boom, and activates one of the indicators if the user command to raise the boom occurs prior to the work vehicle reaching the boom raising start distance from the container.

A system includes a work vehicle, user interface, and controller. The work vehicle includes a frame, boom, implement, perception sensor, position sensor, and ground speed sensor. The perception sensor senses an approaching environment. The position sensor senses a position of the boom or implement. The user interface includes controls and indicators. The controller is coupled to the controls, indicators, perception sensor, position sensor, and ground speed sensor. The controller receives a command to move the work vehicle, drives the work vehicle, determines a distance to the container, determines the ground speed, determines the position of the boom or the implement, receives a command to raise the boom, raises the boom during travel, determines whether the distal end will reach a threshold height before the work vehicle reaches the container, and activates the indicators if the distal end will not reach the threshold height in time.

Method and systems for operating a work vehicle with a selectively interchangeable implement. Image data is captured by a camera (and/or other type of optical sensor) mounted on the work vehicle. The captured image data includes at least a portion of a first implement and the implement type of the first implement is identified by processing the captured image data. Operation information correspond to the identified implement type is accessed from a non-transitory computer-readable memory and an operation of the work vehicle is automatically adjusted based on the accessed operation information for the identified implement type. In some implementations, the implement type is determined by providing the captured image data as input to an artificial neural network and, in some implementations, the artificial neural network is configured to also output an indication of a current operating position of the implement based on the captured image data.

A payload detection system for automated payload tip-off of a loading operation includes a tip-off controller. The tip-off controller is configured to receive a signal of a remaining payload target; receive a signal of a material weight within an implement and a signal of an angle of the implement; and determine a tip-off threshold based on the material weight and the remaining payload target. The tipoff controller initiates a bulk dump sequence if a difference between the material weight and the remaining payload target is greater than the tip-off threshold and initiates a slow dump sequence if the difference is below the tip-off threshold. The bulk dump sequence includes a single implement actuation to induce material spill until the tip-off threshold is met and the material is staged. The slow dump sequence includes a plurality of dump then rack actuations to induce and then prevent material spill until the remaining payload target is met, each dump actuation having an associated dump angle and each successive dump angle is progressively smaller.

Some embodiments include an autonomous loader comprising a speed control system; a steering control system; a shovel control system; and a controller communicatively coupled with the speed control system, the steering control system, and the shovel control system. In some embodiments, the controller has code that instructs the shovel control system to place the shovel in a position to load the shovel; instructs the speed control system to move the autonomous loader into a load zone; determines whether the shovel has been filled with material from the load zone; instructs the shovel control system to raise the shovel a predetermined amount; determines a second time whether the shovel has been filled with material from the load zone; instructs the shovel control system to raise the shovel out of the load zone; and instructs the shovel control system to shake the shovel.

A method for controlling a loading tool includes positioning the loading tool on a lifting device of a machine, receiving a payload by the loading tool from a payload stock during an operating mode, and determining a mass of the payload during the operating mode. The method also includes providing calibration data representative of a ratio between a volume of the payload and a mass of the payload, detecting a volume of the payload during the operating mode, and determining the mass of the payload as a function of the detecting step and the calibration data.

Provided is a work vehicle capable of excavating an excavation object efficiently and in various excavation patterns with appropriate fuel efficiency, regardless of the operator's skill level. The work vehicle includes a controller. The controller executes control including insertion control, acceleration control, and deceleration control. The insertion control keeps the tilt amount (stroke amount S2) of the bucket and increases the lift amount (stroke amount S1) of the lift arm in the insertion period Ph1 from the timing when the work vehicle meets an entry condition for object, where the acceleration α of the vehicle becomes negative, to the timing when the acceleration α first becomes positive. The acceleration control keeps the tilt amount and increases the lift amount if the acceleration condition that the acceleration α becomes positive is met in the lift period Ph2 from the timing when the work vehicle first meets the insertion condition to the timing when the end condition is met, where the lift amount and the tilt amount reach their specified values. The deceleration control keeps the lift amount and increases the tilt amount when the deceleration condition that the acceleration α becomes negative is met in the lift period Ph2.

Upon determining that the work apparatus will not enter a prohibited area set on the basis of output of a second position calculator of a carrier, the system computes, on the basis of the result of a prediction computation, first input of the dynamic characteristic with which a distal end of the work apparatus approaches a target position set on the basis of the output of the second position calculator. Upon determining that the work apparatus will enter the prohibited area, the system computes second input of the dynamic characteristic with which the distal end targets and approaches a position that is closer to the target position than the position of the distal end of the work apparatus at a position different from the target position outside the prohibited area, and the system computes control input for controlling the operation of the loader.

The main controller 100 includes a travel remaining time calculating unit 111 that calculates a remaining time until a target rise/run distance is reached as a travel remaining time t.sub.C, a work remaining time calculating unit 112 that calculates a remaining time until a target arm angle is reached as a work remaining time t.sub.1, a rise/run determining unit 113 that determines whether rise/run is being performed or not, a correction rate setting unit 114 that sets a travel correction rate η.sub.C that adjusts a travel driving torque and a work correction rate η.sub.I that adjusts a work driving torque based on the travel remaining time t.sub.C, the work remaining time t.sub.1, and the rise/run determination flag, and an engine torque distribution calculating unit 115 that calculates a travel driving torque command and a work driving torque command based on the travel correction rate η.sub.C and the work correction rate η.sub.I.

A time period for which an ineffective operation is performed during an excavation work is reduced. A work machine includes a vehicular body, a running wheel rotatably attached to the vehicular body, a work implement operable with respect to the vehicular body, an operation apparatus for operating the running wheel and the work implement, and a controller that controls an operation by the work machine. The controller determines that an ineffective operation in which the work implement does not work is being performed during the excavation work based on an operation command value output from the operation apparatus and notifies an operator of occurrence of the ineffective operation.
